TRIGANOMETRY

The history of algebra goes way back in time (more than 4000 years . Algebra is a sub within mathematics, but for historical reasons, the word "algebra" has three meanings that can all suffice in defining the word or term . Algebra can mean use of letters and symbols to represent values and their relations, especially for solving equations,major branch of mathematics which studies relations and operations or mathematical structure as a "linear" ring, is also called "algebra," or sometimes .algebra is one of main branches of pure mathematics, together with geometry, analysis, topology,statistics and number theory.

Algebra s often taught from anywhere between secondary school to the 12th grade . But does anyone ever stop to wonder were it originated ? Historians trace the roots of algebra back to ancient Babylon society , they developed the first arithmetic mathematical system .It is believed that priests used mathematics and algebra along side their religious rituals. in the 1st millennium BC, mathematicians usually solved such equations by geometric methods, such as those described in the Rhind Mathematical Papyrus, Euclid's Elements, and The Nine Chapters on the Mathematical Art. Much of our knowledge of ancient Egyptian mathematics, including algebra, is based on the Rhind papyrus. This was written about 1650 B.C. The Greek mathematician Diophantus has traditionally been known as the "father of algebra" but in more recent times there is debate over whether al-Khwarizmi, who created the discipline of “al-jabr“, should be considered the “father of algebra “.The Persian mathematician Omar Khayyam is credited with identifying the foundations of algebraic geometry and found the general geometric solution of the cubic equation. With influences and theories from all these different people the renowned math principle used in schools all over his world was...

...sides of similar triangles and discovered some properties of these ratios, but did not turn that into a systematic method for finding sides and angles of triangles. The ancient Nubians used a similar methodology.[5] The ancient Greeks transformed trigonometry into an ordered science.[6]
Classical Greek mathematicians (such as Euclid and Archimedes) studied the properties of chords and inscribed angles in circles, and proved theorems that are equivalent to modern trigonometric...

A Brief History of Trigonometry
A painting of the famous greek geometrist, and "father of measurement", Euclid. In the times of the greeks, trigonometry and geometry were important mathematical principles used in building, agriculture and education.
The Babylonians could measure angles, and are believed to have invented the division of the cirle into 360º.[1] However, it was the Greeks who...

Trigonometry is useful in our world. By exploring where these concepts come from provides an understanding in putting this mathematics to use. The term...

...Trigonometry (from Greek trigōnon "triangle" + metron "measure"[1]) is a branch of mathematics that studies triangles and the relationships between the lengths of their sides and the angles between those sides. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves. The field evolved during the third century BC as a branch of geometry used extensively for astronomical...

...Teaching trigonometry using Empirical Modelling

Abstract
The trigonometric functions sin(x), cos(x) and tan(x) are relationships that exist between the angles
and length of sides in a right-angled triangle. In Empirical Modelling terms, the angles in a triangle
and the length of the sides are observables, and the functions that connect them are the definitions.
These well-defined geometric relationships can be useful when teaching GCSE-level students about
the...

Through investigation of Hitlers psychiatric history its also clear to see that Hitler had not
